Speaking after sentencing, Health and Safety Executive inspector Ian Whittles said: "Kemble Air Services failed to ensure the safety of its employees and others who were carrying out work to decommission fire suppression systems.

"This incident could have been prevented if Kemble Air Services had the appropriate oversight and control of the project to develop the training facility.

"They should have ensured that the work was suitably planned following a full assessment of the risks associated with the work.

"Sadly, their failing to suitably assess the risks and implement the necessary controls led to the death of Mr Mills."

Mr Mills, from Malmesbury, had worked as station officer at the airport for two years and was also a retained firefighter with Wiltshire Fire and Rescue Service.
